As some of you know, I have wanted to stop managing H-M for some time.
It's a tremendous strain on my personal life. I want to set up my own shop.
In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

I have been training VTCNC to run things here. Dabbler is going to learn too.
I feel that they are ready to start taking over the operation.
I will be here to help in case they need, but I don't think they will.
Tony Wells is and will be here also to consult with.
I will be doing backups, upgrades, and installing addons.
Other than that, I will not be around.
I am leaving this place in good operating condition, and financial condition.

hello I saw on the net that many people have built gib crane hoist or gantry crane for workshop you could also help me to build a similar device thanks
measures height under hook 3 meters width 3 metry capacity 2000kg

Looks like a nice design. I would de-rate that weight capacity based on how skilled a welder you are. In an industrial setting, at least in the US, cranes have to be load tested to (I think) 3 times thier rated capacity. If you know how to apply loads and constraints, you can put the design into Fusion 360 and analyze it. I don't expect they will accept any liability if it fails, though.

Most every gantry crane I see LOOKS like it would rack easily from fairly light side loading (parallel with the main beam.) It must not be true, because there are lots of them out there with similar designs, and most of them have probably been tested by ham-fisted fools, and came back for more. I understand that they are not usually more than lightly side loaded. Still, the more they get out of line, the worse the joint loadings get. It would not be a slow failure...

Oh, I see. I was wondering if you designed these and if so, how did you calculate the math and geometry to know the load rating?
[ Oh, capisco. Mi stavo chiedendo se avessi progettato questi e, in caso affermativo, come hai calcolato matematica e geometria per conoscere la valutazione del carico? ]

I have knowledge of traditional engineering and was wondering if you did the calculations yourself or, if you used a computer design tool.
[ Ho conoscenza dell'ingegneria tradizionale e mi chiedevo se hai fatto i calcoli da solo o, se hai usato uno strumento di progettazione per computer. ]

I made an A frame once and discovered real fast that solid hard rubber tires were a mistake. Be sure you use steel or nylon covered steel wheels. The solid rubber ones would flatten out with a load on it...lol made it difficult to roll :-(
